2 Claims.

The present invention relates to a dispensing device designed to receivesealed containers of anti-detonant liquid and make the liquid readilyavailable for introduction into an internal combustion engine. In anordinary internal combustion engine, such as in an automobile, it hasbeen proposed to inject an anti-detonant, such as water, alcohol andother fluids, into the manifold at periods of high octane fuel demand toprevent engine knocking. This injection is automatically controlled,generally by the intake manifold pres sure and therefore requires asmall storage tank for the anti-detonant fluid such as under anautomobile hood. This system permits the use of a lower octane fuel or ahigher compression ratio motor because cruising does not require a highoctane fuel as does acceleration. The octane demand for the latter canbe met by injecting the anti-detonant fluid only when needed. Thus asupply of a gallon more or less of the fluid may be needed with eachtank full of gasoline in a car.

It is the purpose of the present invention to provide an anti-detonantcontainer and dispensing device by means of which the refuelingoperation-can be easily accomplished by using the original container forthe anti-detonant as the supply tank in the vehicle.

Another purpose of the invention is to provide an anti-detonantcontainer and dispenser which readily permits replacement of anexhausted container with a filled and sealed container withoutsubjecting the operator to personal contact with the liquid which mayhave a toxic nature.

More particularly, the invention comprises a supporting cradle adaptedto receive a container and having means associated therewith forpermitting the withdrawal of the liquid and for interchanging fullcontainers for those which have been emptied.

Other features of the invention reside in the novel construction andarrangement of parts hereinafter described and particularly pointed outin the appended claims.

The apparatus may be more clearly understood from the following detaileddescription, taken in conjunction with the accompanying drawings, inwhich:

Figure 1 is a view in side elevation showing apparatus constructedaccording to the present invention;

Figure 2 is a view in end elevation showing the apparatus of Figure 1;

Figure 3 is a detailed view of the puncturing assembly forming a portionof the apparatus shown in Figure 1; and

Figure 4 is a view in side elevation of the-venting assembly, taken atline '44 of Figure 1, and looking in the direction of the arrows.

Referring now to the drawings, a liquid container ll, shown in phantom,is supported in a cradle [2 that may be welded, or otherwise aflixed, toany suitable mounting area l4 under the hood of an automobile. Aflexible strap 15, adapted to pass around the container II and retain itsecurely in cradle I2, is pivotally fastened at one end to the cradle byany suitable means such as hinge l6. A reinforcing plate I! having aprojecting lug therein is fixed to the free end of the flexible strapIS. A threaded bolt I9 pivotally secured to the cradle by hinge isadapted to pass through the opening in the lug l8 and is provided with awing nut 2 l A nut 24 adapted to receive a wing bolt 25 is fixed to andsupported by flexible strap l5. The wing bolt 25, pointed at one end 26,has a passageway 21 drilled therethrough, the passageway 21 turning offat right angles to the axis of the bolt near end 26, as shown in Figure4.

At the bottom of the cradle 12, an aperture 28 is provided to receive anipple 33 extending from the container H. The nipple engages a collar 3!by means of threads 32. Collar 3| is rotatably secured to a flange 34formed on a receiver 35 to removably retain the receiver 35 against thelower end of nipple 30. A puncture pin 36 having an enlarged portion 31and a threaded portion 38 is positioned in the base plate 39 of thereceiver 35, the base plate having a threaded hole and a conicallyshaped valve seat complemental to the enlarged portion 31. A washer 40provides a seal between the nipple 3!] and the open end of the receiver35.

One end of a flexible connection 4| is in threaded engagement with anipple 42 on receiver 35. The other end engages a T member 44 which ismounted on an end plate 45 on the cradle I 2. One arm of the T 44supports a vented sight glass 46, the other arm is connected to a draincontainer 41 and to an outlet connector 49. A suitable liquid flowcontrol mechanism, not forming a part of the present invention, may beconnected to outlet 49. To enable the visual determination of the liquidremaining in the system, drain container 41 may, in a typicalembodiment, be made of glass or any other suitable transparent material.

l8 with an opening In operation, container II is placed on the cradle l2and secured therein by tightening wing nut 2| until the flexible strap 5securely engages the periphery of the container.

Puncture pin 36 is turned to move in an upwardly direction "to puncturecontainer H, and then turned in the opposite direction until theenlarged portion 31 thereof rests in the recessed portion of the baseplate 39 of the receiver 35. This serves to prevent liquid from leakingthrough the bottom of the receiver 35.

Wing bolt 25 is screwed into the container H to provide a vent throughpassageway 21, thereby permitting flow of the liquid from the containerll through connection 41 and the drain container .1 to outlet connector49. By means of sight glass 46, the liquid level in the container 1 Ican be easily viewed.

From the foregoing it is apparent "that the present invention provides anovel container and dispensing device which permits easy replacement ofa liquid-supply as we11 as a'simple and highly eifective means forcontrolling the flow. Further, the invention provides an invaluable aidin the processin of liquids having harmful or injurious effects to thehandlers, inasmuch as any personal contact is eliminated.

ihough the invention has been described with specific reference to theaccompanying drawings, it is to be understood that the typical form ofthe invention described above can be modified considerably Withoutdeparting from the principles of the invention. Obviously, variousshaped containers can be employedeach having a cradle conformingthereto, and the cradle may be composed of a unitary or built-upstructure.

We claim:

1. A device fordispensing liquidrfrom a sealed container'which'comprisesa cradle for supporting said container in liquid dispensingposition,means for venting said container above the level of theliquidthereinwhileit is retained in said position, said means havinganangularpassageway for preventing the escape of liquid from the top ofthe containenrneans associated with the cradle for puncturing 'saidcontainer below the level of the liquid therein, saidimeans comprising areceiver adapted to be sealed to the container and having a recessfacing the container in one wall thereof, a puncture pin projectingthrough said recess and movable longitudinally within said receiver,said puncture pin being adapted, upon movement thereof against the 4container, to puncture the container at a point enclosed by the receiverand having an enlarged portion complemental to said recess to form aliquid seal when the puncture pin i retracted from the container, andmeans for conducting liquid from said container through said'receiverand to an outlet connection.
